Renal cell carcinoma shows typical solid ultrasonic pattern. A, nephrotomogram demonstrates mass in right lower pole. B, arteriogram reveals tumor neovasculature. C and D, nephrosonograms show typical pattern found with solid masses.

Renal cyst shows typical cystic ultrasonic pattern. A, nephrotomogram demonstrates lucent mass in left upper pole. B, contrast in cyst outlines cyst wall. C and D, nephrosonograms show typical pattern found with cystic masses.

5. Fig. 4
Renal abscess shows typical complex ultrasonic pattern. A, IVP demonstrates mass in left upper pole. B, arteriogram reveals mass to be avascular. C, nephrosonogram with tracing at low gain suggests cyst. D, tracing at high gain reveals extra echoes consistent with complex type of mass.

Polycystic disease. A, IVP and B, nephrographic phase of arteriogram demonstrate typical findings. C, low gain suggests cystic pattern. D, high gain shows complex ultrasonic pattern consistent with polycystic disease.
